Comment (by shahabdev):

 The issue you’re facing is likely related to how WordPress handles
 taxonomies internally when using category__in. Before calling get_posts(),
 WP_Query constructs a straightforward SQL query that retrieves posts
 matching the specified categories. However, after calling get_posts(),
 additional joins appear because WordPress expands its query structure to
 ensure proper filtering, especially when multiple taxonomy terms are
 involved.
